GOLLAPSIBLE TUBE.

Specification of Letters Patent. 7

Patented Mar. 26, 1912.

Application filed March 30, 1910. Serial No. 552,465.

To all whom it may concern:

Be it known that I, HERBERT W. SNOW a citizen of the United States,residing at Somerville, in the county of Middlesex and State ofMassachusetts, have invented a new and useful improvement in acollapsible tube having telescoped on its cup-shaped end a detachablecap which encircles and is firmly fastened to the handle of a smallbrush. This tube is intended to be used for holding and distributing bythe aid of said separable brush adhesives, gummy liquids, paints, oils,or any other soft substances which may be inclosed with,- in the tube, afull description of which invention I give in the followingspecification and drawings.

This invention relates to a collapsible tube having a large cupreceptacle at one end to be used as a supplementary reservoir, theinterior of which is connected to the tube by means of a small hole. Thereceptacle or reservoir mentionedis intended to hold part of thecontents of the tube as it is pressed out through the hole from the tubeand on to the brush which is inclosed within the reservoir bymeans of acap which is fastened to the handle of the brush, or cast, stamped, orturned with the handle in one or two pieces, and which, when coveringthe open end of the reservoir by sliding or telescoping over the outeredge of the same, excludes the air from the inside sufficiently to keepthe brush soft and the contents of the reservoir to about the sameconsistency as that contained within the tube itself and ready forimmediate use. By simply pulling off the cap, the brush with the handleand cap attached becomes entirely separate from the tube and acts as adistributer; it being a convenient article to use and easily replaced onthe reservoir end of tube again with the brush directly in the softsubstance inclosed within the supplementary reservoir. 45

In the accompanying drawings,-Figure 1 is an elevation of my tube whichin this view is shown as an empty tube with cap closing thesupplementary reservoir at the end of the tube. Fig. 2 is a central,vertical section of Fig. 1. Fig. 3 is a horizontal section looking downon the tube I and on the brush cap IV and handle of brush V which isresting on the reservoir end of the tube. Fig. 4 is a horizontal sectionlooking upward at tube I at the bottom of the tube and into it, showingthe opening III into the pastes,

reservoir at the other end of the tube. Fig. 5 shows the tube with thebottom turned up or closed as it would appear when filled with anysubstance. Fig. 6 represents the brush with handle and cap after beingraised off of the end of the reservoir end of the tube. Fig. 7represents the brush, with the cap as it might be made with slanting orprojected sides.

I Most collapsible tubes made have a direct passage from the outsideatmosphere to the substance inclosed within the tube, thus causing thesaid substance to harden within .the tube and around the opening ofsame.

In my invention it will be found that, because of the large amount ofthe substance that can be kept in immediate or close proximity to thebrush all the time, there is no difliculty in keeping the brush softwith the 'said substance so long as the cap of the brush is put securelyon to the reservoir of the tube when not in use. And it will also befound that this reservoir end of the tube is of sufficient size to allowof the stirring of said substance which has been pressed therein fromthe main tube, thereby gaining a more uniform mixture than would befound on a brush which has been withdrawn directly from a large body ofany substance whatsoever.

The tube specified I make of one piece of metal, though it might be madeof two pieces screwed or fastened together at the junction where themain tube and the reservoir end meet, aluminum being preferred, althoughtin, or lead, or other metal may be used for it. The cap and handle ofthe brush is made of any of the above-mentioned metals, aluminum beingpreferred for this also. The so-called bristles, or other brushmaterial, is fastened into the lower part of the metal handle securely.

In the drawings, the reference numeral I designates the main tube,.IIthe reservoir end of the tube, III the entrance from the main tube tothe supplementary reservoir end of the tube, IV is the cap of thereservoir on the brush handle, showing the vertical sides of the samewhich may be slanting or projected at the bottom edge, sometimes. Itwill readily be understood that by making the sides of the cap flare outsomewhat, I do not depart from the general arrangement, but simplyprocure for the top of the supplementary reservoir end a loose fittingcap, when needed, and it will be apparent thatsponge may be used insteadof bristles for the brush.

Having thus described my invention, what I claim as new is as follows:

1. A collapsible tube which has a projection or supplementary reservoirat one end shaped like a cup, and an opening extending from thecollapsible section to said reservoir for the purpose of keeping thereservoir supplied by pressure on the collapsible section with part ofsaid sections contents in such proportions as to thoroughly surround thebrush with the liquefied mass; a movable cap to cover the end of thereservoir having a handle and brush attached, said cap to slide oneasily over the smooth edge of the reservoir, thus allowing said brushto be placed into the reservoir easily and quickly wholly immersed inthe reservoirs contents at all times when not being used, the reservoirbeing large enough to allow any substance within to be stirred up withthe brush it necessary before using it.

2. An apparatus of the character specified, comprising a collapsibletube, a neck formed on one end of said tube, provided with an openingcommunicating with the tube, a cup attached to said neck provided with abrush which projects into said cup as far as the opening to the tube,and a cap attached to said brush for the purpose of closing the cup.

In testimony whereof I have afliXed my signature, in presence of twowitnesses.
